And another! apparently you use the distributive property to remove the parentheses.
- ( - 6 v - 4 w + 4 )

6v+4w-4
Because you do -*-6v=positive 6v then -*-4w=positive 4w and then -*4=-4 and that takes care of the parenthesis
Basically you multiply the outside number or sign by all things inside the parenthesis
So in this problem you multiplied the negative sign by all the things inside the parenthesis

After subtracting 247 from 538, we will get 291.

Step-by-step explanation:

We are asked to subtract 247 from 538.

Convert in a subtraction problem:

  538

 -247

Now, we will subtract each digit in the lower line from upper line as:

  538

 -247

   291

Therefore, the answer to our given problem would be 291.
